dynamic zipcode option to a weather plugin

Question

I am trying to use a weather plugin: http://jsfiddle.net/fleeting/a4hbL/light/

which asks for either zipcode or woeid. I don't want to hard wire the zipcode there. I would rather zip code is dynamic so people spread over various locations can use the site, with the plugin working for their location. I am trying to auto detect their location using their IP and a webservice that geolocates based on IP.

$.getJSON('http://freegeoip.net/json/', function(data) {
  var items = [];
  var zip = data["zipcode"]; 

});

I need to pass the zip to the plugin below: $.simpleWeather({ zipcode: 'zip', ... });

Answer 1

There is no below, $.getJSON is async, so you do it in the success handler :

$.getJSON('http://freegeoip.net/json/', function(data) {
    $.simpleWeather({ zipcode: data.zipcode });
});
